Poison Hemlock Question Again

[ship4brains]

We bought 10 acres last August. This spring it exploded. I sprayed with 24d and surfactant. Took two applications about 4 weeks apart but it didn't survive.

FYI, relatives purchased property years ago that was covered in hemlock....bought goats to clear it. They died.

I looked up the definition of pith and pithy, and Tom's description is accurate. Mark.

It can grow 6'-8' tall the 1" stalk is tubular and the inner core is a pith when dry. One year back in the 80's when we had the ozone hole I became particularly allergic to the stuff and broke out something furious from driving through a dry stand of it with a tractor.

That's where I am essentially: No sap if its brown and dry (killed by Glyphosate) so you don't have to worry about that) but if you whack it seems to me you generate dust that can cause you a problem as you mentioned if (your) not protected. Most of it I can leave it where it is but I have some farm implements that I need to access and that is where I will have to figure out the best approach.

Long sleeve shirt, gloves and a dust mask, break the stalks off and move them some place to rot down, or some area were you can drive over them with a tractor to crush them into the ground
If the stalks are still flexible use pruning shears to cut them into stalks

I would believe the info from official sources. You could call your county agent and maybe talk to a human that knows. Seems like a really bad invasive.

That should be true but county agents have become no more than another bureaucrat leeching off taxpayers. .
In conversation with two public school ag teachers and county agent at County Fair Livestock Auction, I asked what if anything has been found that allows cattlemen to determine whether Johnson Grass is safe to graze. Both ag teachers said they always thought a test should be possible but wasn't aware of one. County agent said he recommends the least valuable animal in herd be allowed to graze one or more hours before allowing remainder of herd to graze.
If that man isn't worthless as boar hog nnalert , I can't think of a better example.

I totally share your opinion of County Ag. Agents, even though the one here is (seems to be) sponsored by TAMU, the state Ag. school. Have had this opinion for decades. Back when I first had this farm, I had a bad erosion problem with the discharge from my pond dam. I worked out a solution and submitted photographs of it functioning during a heavy rain and figured that would be good information for other folks with dams in Blackland Clay like mine. Never heard from the agent, not a peep!!!!!!! In working through this current problem I thought I'd look him up and see what's available from his office......No change from decades ago.....totally worthless even trying to reach him !!!!!

I decided to bite the bullet today and snipped off a stem with 5 totally dead, dried out, rosettes. It seems that the rosettes have 5 flowers with 5 pedals each and each generates a seed....and yes they are small...rosettes were about 1 1/2" in circumference, and seeds were about 1mm long and hairy. Just for my personal information, I thought about planting a few of them in a flower pot just to see if killing the plant with Glyphosate had any affect on the germination ability of the seeds......may do that before this is all over.

I have pulled up many, many, pictures of good and bad leaves on the www and can't really tell them apart. In canvasing my pastures, I see growth of something starting to come out of the ground and I would like to know what it is so that I can develop a plan for next year when this years plant's seeds develop their plants....get them before they develop their buds is the idea. I guess I'll just have to wait and watch when they emerge.
